I installed version 8 of SC and successfully connect to AD and sync desired users into SC security database. However the AD username with password cannot work. Is there any hints for me?
Assuming you installed it on a windows server you should check whether you can access your ad server from the account under which your scriptcase apache server is running.
So if you have a user that can run ad connection by hand checking via a commandline (e.g. with a vbs script or something like that) then you should be able to do that on sc as well.
We had to create a special user with some extra rights to allow our LDAP to work. That user then is used to run the apachescriptcase service.
My Mac is connecting to AD and tried that it can connect to AD via Directory Utility and also can sync users from AD by ScriptCase. Any more hints?
